Tracker500/500i User Manual
40
Indicated heading does not
match the boat’s compass.
No/low fuel flow indicated.
Only one flow rate value shown
for a twin engine installation.
Erratic fuel flow readings.
No fuel economy reading.
Fuel Remaining does not match
the amount left in the tank.
The boat must be moving before the Tracker500/
500i can determine its direction.
The Tracker500/500i BEARINGS setting must be
set to MAG before the indicated heading will match
the compass.
The constantly changing SA offset results in an
indicated heading error, usually apparent only at
low speeds.
The Tracker500/500i indicates the boat’s direction
of movement over the sea bed. External influences
such as tidal currents and wind induced leeway
mean that this may not be the same direction that
the boat is pointing in, which is what a compass
indicates.
Magnetic materials on the boat may influence a
compass but not a Tracker500/500i.
Check that the 5 pin fuel transducer connector is
fully inserted into its socket on the back of the
Tracker500i.
Check that the fuel filter(s) in the line are clean.
Ensure that the fuel flow transducer has not been
exposed to excessive heat or vibration.
In the Fuel sub-screen under Setup you must have
ENGINES set to two.
The mounting position of the fuel flow transducer
must not be too close to the fuel pump(s) and not
subject to excess vibration.
Check for air leaks in the fuel hose(s) or fuel pick-
up(s) in the tank(s).
The filtering level (averaging) has not been set to
suit the engine(s). In the Fuel sub-screen under
Setup, increase the FLOW FLTR value until a
steady flow rate is indicated.
Check the fuel flow readings are not zero.
For the Tracker500i to be able to calculate an
economy reading, the boat must be travelling
above 5 knots, or above 1 knot if a differential
receiver is in use.
Fuel Remaining must be set to the amount of fuel
on board after every refueling.
Engine has been run without the Tracker500i
turned on to record the fuel usage.
Fuel transducer calibration is required when the
Tracker500i is first installed.
